Test Catalog

Test Name

Test ID: FBL    
Fungal Culture, Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

Diagnosis and treatment of the etiologic agents of fungemia


Select patient population that presents with signs and symptoms of sepsis, especially fever of unknown origin

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

When this test is ordered, the reflex test may be performed and charged.

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Due to the high mortality rate from fungemia, the expeditious detection and identification of fungi from the patient's blood can have great diagnostic prognostic importance. Risk factors for fungemia include, but are not limited to, extremes of age, immunosuppression, and those individuals with burns or indwelling intravascular devices.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.


If positive, notification is made as soon as the positive culture is detected or identified.

Interpretation Provides information to assist in interpretation of the test results

Positive cultures of yeast and filamentous fungi are reported with the organism identification.


Positive cultures are usually an indication of infection and are reported as soon as detected. Correlation of culture results and the clinical situation is required for optimal patient management. A final negative report is issued after 30 days of incubation.

Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

No significant cautionary statements
